The lower section is set apart to show the Oblong Square itself. The first three signs, Cancer, Virgo, Leo are feminine and the next four, Libra, Scorpio, Sagittary, Capricorn, are masculine. The sum of the squares of the first three and the next four is equal to the square of the hypotenuse which, itself, is actually equal to five and conforms to the five unmanifested signs representing the Royal Arch. As is readily seen in the plate, the hypotenuse is equal to one side of the square capable of encompassing the circle. It is the total sum of the Mason’s work on the Oblong Square, the trestle-board, his lodge, his body, which squares the circle and enables him to take his rightful place as the Keystone in The Royal Arch in The Realm of Permanence.
